First the librarians told Kurtz yes, come look. But by the time Kurtz landed in Chicago, the librarians changed their minds. The donor of the documents hadn’t cleared his research. Perhaps they’ll let him look at the documents on Nov. 5.

The relationship between the ambitious Obama and the unrepentant Ayers is a subject that excites Republicans, who haven’t really thwacked that pinata as hard as they might. It really irritates Obama and his political champion, Chicago’s sovereign lord, Mayor Richard M. Daley.

“This is a public entity,” Kurtz told us Wednesday. “I don’t understand how confidentiality of the donor would be an issue.”

You don’t understand, Mr. Kurtz? Allow me to explain. The secret is hidden in the name of the library:

The Richard J. Daley Library.

Eureka!

The Richard J. Daley Library doesn’t want nobody nobody sent. And Richard J.‘s son, Shortshanks, is now the mayor.
